Not at a time. The truck can use street-space, make noise and pollute while driving around with a load of packages that is going to other addresses than the one it is currently heading to. The truck will probably travel a smaller distance in total than all the drones would, but my guess is that the total impact of the truck driving around is larger that the total impact of the drones. In particular if they manage to make the drones less noisy. The best is probably a hybrid system where a truck filled with drones charged with packages drives to the right part of the town and releases all the drones for the last kilometers of transport.
